, TBI METHOD 0F PRODUGING THE SE.

To all whom it may concern.'

Be it known that I, Fnnous F. WILSON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Matrices and Methods of Producing the Same, of'wlnch the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to the production of type matrices for use more particularly I in type casting, linotype machines, and the like, and the invention has in view especially the punching of large character matrices, the formation of which has been attended with considerable diliiculty by reason of the great amount of metal displaced i n the punching operation, and the1 inability to properly control the direction of the iow of the displaced metal.

It has been particularly difficult to cause the metal to iow up into the counters or cavities in the punch, of such letters as O, R, B, P and the like; and also ithas been difficult to prevent the displaced metal from owing laterally and deforming or distorting the blank. It' is of the utmost importance that the counters shall stand at a high level in the matrices to make deep\ cavities in the type, otherwise these por` tions ofthe type standing vat a high level will receive ink and transfer it to the paper. It is also of importance that the matrix body preserve its original dimensions and that the character therein occupy accurate' and very definite relations to the ends and sides of thc same.

The aim of my invention is to obviate the difficulties mentioned, andv to form matrices with high counters, without distorting or deforming the body or blank, and the invention consists of an improved means and method of procedure and the matrix produced thereby, in which method'thepmetal of the blank displaced by the punch in the forming action, is allowed to flow into a relief cavity or cavities and in this way be controlled in its direction of flow. As a result the metal of the blank opposite the high points of the punch, will, when the punch is driven into the blank, sink into the relief cavities and will thus be prevented from being displaced laterally and distortingv the Specification of Letterslatent.

the depressions in the punch 'will be supported by the solid metal of the blank beneath, and will be caused to stand up and flow into and completely fill the depressions in the punch and thusv form proper high standing counters in the matrix.

In the accompanying drawings l have represented different means embodying my invention and by which, my improved method may be carried into e'ect, but it will 'be understood that the invention may be embodied in other forms and constructions than those shown, and that the invention is not limited to any particular details or construcitions except in so far as such limitationsv are specified in the claims.

ln the accompanyingdrawings: Figure l f is a perspective view of the matrix blanksupporting member formed to receive the matrix blank. Fig. 2 is a similarview showing the supportingfmem lank separated, and the supporting member provided Fig. 4 is a sectional view of the` ation. Fig. 5 is a similar view showing the J punch entered in the blank and with the relief cavities in the supporting member ffilled with the displaced metal. Fig. 6 isa perspective view of the finished matrix. Fig. 7

'is a-perspective view of the matrix blank showing the relief cavlties formed ltherein instead of in the supporting member.

Referring to the. drawings: In4 carrying my invention into effect I provide a supporting member A, adapted to sustain a matrix blank B, in which the' matrix character is to be punched. The supporting member in the example shown `is of the general form and contour of the usual and well lknown circulating linotype matrices as represented for instance in Letters Patent of the United States to Ottmar Merganthaler, No. 436,532, although in the example illustrated the body'is more massive the forming punch, theblank will be caused to expand and be tightly to carry larger characters The matrix blank B, is in the form cfa flat plate of suitable material, preferably metal re1a. tively softer than the supporting member so that. the matrix may be readily punched therein. The blank B is adapted to be inserted in an open slot or recess a, formedin the edge of the supporting member having a fiat supportin bottom surface, and when inserted and su jected to the action of that the metal of the blank will'be displaced and will flow laterally as the hi h points of the punch sink into the blank, orming corresponding'depressions therein. By reason oftheiconsiderab'le size of the character on the punch, and the fact that the punching action is a violent one, al great amount of metal is displaced, and as there are no means to control theflow of the displacedmetal, it has been found in practice that the blank will become deformed or distorted, and the' metal will f ail to flowk up into and properly fill the counters in the punch, 'more particularly of such letters as 0,'R, B, P, and the like. In

accordance with-my inventionI obviate these objectionable actions by providing relief cavities or recesses between the blank and supporting member, by which means I the direction of low. of the displaced metal iscontrolled, being caused to iiow in the direction of the action of the punch. As a result, the lateral iow of the metal in such degree as to cause deformation or distortionofthe blank will be prevented, and the portions of the blank between therelief cavities or recesses being supported by the solid `metal beneath, will be caused to stand up and completely and properly lill the counters in the punch.

y The relief cavities vmay be of `different forms and differently applied. For instance they may. take the general form l,and contour of the character or characters which are to be "produced, and be either formed in the bottom of the recess in the supporting memberV as shown. in Fig. 2, or they may 'be .formed in the under face of the blank itself, as shown in Fig. 8. Relief cavities when in this form may be produced by driving the punch a'moderate distance into the bottom of the recess. in the supporting membei', or into the under or reverse' side of the action,- the supporting tom ofthe recess in the supporting member,

orthey may be formed in the under face of the blank, their location being preferably opposite the portions of the blank where the 'high points of the' punch will strike in forming the'matrix.. i y

In carrying my invention into effect when the relief cavities are of the form, and applied as shown in Fig. 2, the blank being inserted in-,place in the recess over the' cavif ties vasshown in Fig. 3, the supporting member and inserted blank Iare held firmly in fixed position by the clamping jaws C as shown in Fig. '4. The punch is now forced or driven into the blank,.with the result that the metal of the blank directly acted on and displaced by the high or relief portions of the punch will flow and sink into the corresponding relief cavities in the supporting member beneath, and the adjacent portions of the blank between and surrounding the high points of the punch will be supported lby the solid metal of the supporting body beneath, and these supported portions will be caused to flow up and completely fill the counters in the punch as shown in Fig. 5; at the same time the blank will be expanded and caused to seat tightlyin the recess in thesupporting member, and a matrix of the form shown in Fig, 6 will be produced.

The above described actions will be substantially the saine in cases Where the relief cavities are formed in the inner or under face of the blank, and also in cases where' l of the flow of the displaced metal, so that the objectionable, undue lateral flow of the displaced metalwill be prevented, and the portions of the blank adjacent those acted on by the high points of the punch, will be supported and caused to stand up and properly fill the counters in the punch.

While I have shown by way of example the supporting member for the matrix blank in the general form of the well known linotype matrix, and While I have described the practice ofmy improved method in connection with a supporting member of'this form, it will be understood that other forms of supporting members may be employed without de arting from the limits of my invention, t e form shown adapting the matrix t0 be employed in connection with the usual and normal sized matrices in linotype inachines of the character mentioned.
